GtkTreeDragSource is implemented by GtkListStore, GtkTreeModelFilter, GtkTreeModelSort and GtkTreeStore. GtkTreeDragDest is implemented by GtkListStore and GtkTreeStore.

Detailed Description

GTK+ supports Drag-and-Drop in tree views with a high-level and a low-level API. The low-level API consists of the GTK+ DND API, augmented by some treeview utility functions: gtkTreeViewSetDragDestRow, gtkTreeViewGetDragDestRow, gtkTreeViewGetDestRowAtPos, gtkTreeViewCreateRowDragIcon, gtkTreeSetRowDragData and gtkTreeGetRowDragData. This API leaves a lot of flexibility, but nothing is done automatically, and implementing advanced features like hover-to-open-rows or autoscrolling on top of this API is a lot of work. On the other hand, if you write to the high-level API, then all the bookkeeping of rows is done for you, as well as things like hover-to-open and auto-scroll, but your models have to implement the GtkTreeDragSource and GtkTreeDragDest interfaces.
